UK ETA vs Other Electronic Travel Authorisations Worldwide

The Rise of Electronic Travel Authorisations Around the World

Electronic travel authorisation systems are becoming the global standard for managing visa-free travel. Instead of requiring travellers from low-risk countries to obtain a full visa, these systems use a simple online application to screen visitors before they board their flight. The United Kingdom’s ETA is the newest member of this growing family of digital pre-screening programmes.

This guide compares the UK ETA with every major electronic travel authorisation system worldwide, including the US ESTA, Canada eTA, Australia ETA, New Zealand NZeTA, and the upcoming EU ETIAS. Whether you are planning a multi-country trip or simply want to understand how the UK system compares, this comprehensive comparison has you covered.

For detailed information about the UK ETA specifically, see our complete UK ETA 2026 guide.

Complete Comparison Table: All Electronic Travel Authorisations

The following table provides a side-by-side comparison of every major electronic travel authorisation system currently operating or planned worldwide:

UK ETA: The Newest System

The UK Electronic Travel Authorisation was introduced in phases starting with Qatar in October 2023. It expanded to Gulf Cooperation Council (GCC) countries in February 2024, then to all non-European visa-exempt nationals in January 2025, and finally to European nationals in April 2025. Full enforcement began on 25 February 2026.

Key features of the UK ETA:

• Cost: £16 (planned increase to £20, date not yet confirmed)
• Validity: Two years or until your passport expires
• Stay limit: Six months per visit – the most generous of any electronic travel authorisation
• Application: Online via the official portal or through the UK ETA app
• Purpose: Tourism, business visits, short-term study, transit, and medical treatment

US ESTA: The Pioneer

The United States Electronic System for Travel Authorization (ESTA) was launched in 2009 and is often considered the original electronic travel authorisation. It paved the way for similar systems around the world.

• Cost: $21 USD (approximately £17)
• Validity: Two years
• Stay limit: 90 days per visit under the Visa Waiver Program
• Eligible countries: 41 countries in the Visa Waiver Program
• Key difference from UK ETA: The US ESTA limits stays to 90 days, compared to six months for the UK ETA. The ESTA also requires more detailed personal information, including employment history and social media accounts.

If you are planning a trip that includes both the US and the UK, you will need both an ESTA and a UK ETA. These are completely separate systems with no mutual recognition. For a detailed comparison, see our article on UK ETA vs US ESTA.

Canada eTA: Best Value

Canada’s Electronic Travel Authorization (eTA) launched in 2015 and is notable for its low cost and long validity period.

• Cost: C$7 (approximately £4) – the cheapest system
• Validity: Five years – the longest validity of any system
• Stay limit: Six months per visit
• Eligible countries: Citizens of visa-exempt countries (similar list to the UK)
• Key difference from UK ETA: The Canada eTA is significantly cheaper and valid for longer. Like the UK ETA, it allows six-month stays. It is required only for air travel – travellers arriving by land or sea from the US do not need one.

For a detailed comparison, see our article on UK ETA vs Canada eTA.

Australia ETA: App-Only Application

Australia has operated electronic travel authorisation systems since 2008, making it one of the earliest adopters alongside the US. The current system requires applicants to use a dedicated mobile app.

• Cost: A$20 (approximately £10)
• Validity: One year – the shortest validity period
• Stay limit: Three months per visit
• Application: Must be submitted through the Australian ETA app (no web application)
• Key difference from UK ETA: Australia’s system has the shortest validity (one year vs two for the UK) and the shortest maximum stay (three months vs six). The app-only application can be problematic for travellers without compatible smartphones.

New Zealand NZeTA: Variable Pricing

New Zealand introduced its NZeTA in 2019 alongside the International Visitor Conservation and Tourism Levy (IVL).

• Cost: NZ$17 (app) or NZ$23 (online) plus NZ$100 IVL – the most expensive overall
• Validity: Two years
• Stay limit: Varies by nationality (typically up to six months for some, three months for others)
• Key difference from UK ETA: New Zealand charges different prices depending on whether you use the app or website, and the additional IVL fee makes it the most expensive system overall. The IVL funds conservation and tourism infrastructure.

Travellers visiting both Australia and New Zealand need separate authorisations for each country. Our guide for Australians and New Zealanders visiting the UK explains what Antipodean travellers need to know.

EU ETIAS: The Coming System

The European Travel Information and Authorisation System (ETIAS) has been in development since 2016 and is expected to launch in 2026 or 2027. It will cover all 27 EU member states plus Iceland, Liechtenstein, Norway, and Switzerland (the Schengen Area).

• Cost: €7 (approximately £6) – one of the cheapest planned systems
• Validity: Three years (planned)
• Stay limit: 90 days within any 180-day period across the entire Schengen Area
• Eligible countries: Citizens of about 60 countries currently exempt from Schengen visas
• Key difference from UK ETA: ETIAS will cover an entire bloc of 30+ countries with a single authorisation, whereas the UK ETA covers only the UK. ETIAS will use the 90/180-day rule, which is more restrictive than the UK’s six-month allowance.

British citizens will need ETIAS to visit EU/Schengen countries once the system launches. For a detailed comparison with the UK ETA, see our article on UK ETA vs EU ETIAS.

Other Countries with Electronic Travel Systems

Beyond the major systems, several other countries operate or are developing similar programmes:

• South Korea (K-ETA): Launched in 2021, currently suspended for many nationalities but may be reinstated
• India (e-Visa): While technically an electronic visa rather than an ETA, India’s system allows online applications for tourism, business, and medical purposes
• Sri Lanka (ETA): One of the earlier adopters in Asia
• Kenya (eTA): Launched in 2024 as Kenya abolished traditional visas for most nationalities
• Oman (eVisa): Electronic visa system for tourism and business

The trend is clear: more countries are adopting electronic pre-screening systems as a modern alternative to traditional visas. This makes travel more accessible while maintaining security.

What Multi-Country Travellers Need to Know

If you are planning a trip that covers several countries with electronic travel authorisation systems, here is what to keep in mind:

No Mutual Recognition

Each electronic travel authorisation is completely independent. Having a US ESTA does not exempt you from the UK ETA, and vice versa. You must apply separately for each country’s system.

Different Application Timelines

While most systems process applications quickly, processing times vary. Apply for all authorisations well before your departure date. A good rule of thumb is to apply at least two weeks before travel.

Passport Changes Affect All Systems

All electronic travel authorisations are linked to your passport. If you get a new passport, you must reapply for every system. Make sure your passport will remain valid throughout your entire trip.

Example: Europe and UK Trip

A common itinerary involves visiting both the UK and European countries. Here is what you might need:

• UK ETA (£16) for the United Kingdom
• EU ETIAS (€7, once launched) for Schengen countries
• Separate visa if visiting non-Schengen, non-EU countries

Plan your documents early. Our transit rules guide explains what happens if you pass through the UK on the way to Europe.

Example: Round-the-World Trip

For a round-the-world trip covering the US, Canada, UK, EU, Australia, and New Zealand, you would potentially need:

• US ESTA ($21)
• Canada eTA (C$7)
• UK ETA (£16)
• EU ETIAS (€7, once launched)
• Australia ETA (A$20)
• New Zealand NZeTA (NZ$17–23 plus NZ$100 IVL)

The total cost of all electronic authorisations for such a trip would be approximately £100–120, which is still far less than applying for traditional visas for each country.

The Global Trend Towards Pre-Screening

Electronic travel authorisation systems represent a fundamental shift in how countries manage their borders. The key benefits driving adoption include:

• Security: Pre-screening allows authorities to check travellers against security databases before they board their flight
• Speed: Applications are processed in minutes rather than weeks
• Cost: Far cheaper than traditional visas for both governments and travellers
• Convenience: No need to visit embassies or consulates
• Data collection: Governments get advance information about who is arriving

Experts predict that within the next decade, most developed countries will operate some form of electronic pre-screening for visa-free visitors. The UK ETA is part of this global movement towards smarter, more efficient border management.

How the UK ETA Ranks Overall

Compared to other systems, the UK ETA is competitive in several areas:

• Most generous stay: Six months per visit, the joint longest with Canada
• Mid-range cost: £16 places it in the middle of the pack
• Standard validity: Two years is in line with most systems
• Flexible application: Both online and app options available
• Fast processing: Most applications approved within minutes

The main drawback compared to some systems (particularly Canada eTA) is the higher cost. However, the UK ETA’s generous six-month stay limit and relatively simple application process make it one of the more traveller-friendly systems worldwide.

Frequently Asked Questions

Do I need both an ESTA and a UK ETA for a US-UK trip?

Yes. Each country requires its own electronic travel authorisation. Apply for both before your trip.

Will the EU ETIAS replace the UK ETA?

No. The UK is not part of the EU or the Schengen Area. The UK ETA and EU ETIAS are completely separate systems. You may need both if visiting the UK and Europe.

Which electronic travel authorisation is the cheapest?

Canada’s eTA at C$7 (approximately £4) is currently the cheapest. The EU ETIAS at €7 will be similarly affordable once launched.

Can one authorisation cover multiple countries?

Only the EU ETIAS (once launched) will cover multiple countries with a single authorisation, as it applies to all Schengen Area countries. All other systems are country-specific.

What happens if my ETA for one country is refused?

A refusal from one country does not automatically affect your application for another. However, some application forms ask about previous visa or travel authorisation refusals. Always answer honestly. If your UK ETA is refused, see our ETA refused guide.

Tips for Managing Multiple Electronic Travel Authorisations

If you travel frequently to countries with electronic travel authorisation systems, keeping track of your various authorisations can become complex. Here are some practical tips:

• Create a travel document spreadsheet: Record the country, authorisation type, issue date, expiry date, and the passport number it is linked to. This gives you a quick reference for planning trips.
• Set calendar reminders: Add expiry dates to your calendar with reminders several weeks before. This ensures you have time to reapply before your next trip.
• Keep confirmation emails: Save all approval emails in a dedicated folder. While authorisations are linked to your passport digitally, having the confirmation email provides peace of mind.
• Apply early for new trips: Even if you already hold a valid authorisation, double-check its status before each trip. Authorisations can be revoked if your circumstances change.
• Consider passport renewal timing: Since all electronic authorisations are linked to your passport number, getting a new passport means reapplying for everything. If your passport is due for renewal, consider timing it so you only need to reapply once.

The cost of maintaining all major electronic travel authorisations simultaneously is modest compared to traditional visa fees. For frequent international travellers, these systems represent a significant improvement in convenience and cost over the traditional visa application process.

Summary

Electronic travel authorisations are now the standard way for developed countries to manage visa-free travel. The UK ETA joins established systems in the US, Canada, Australia, and New Zealand, with the EU ETIAS set to launch soon. Each system operates independently, so multi-country travellers should plan ahead and budget for multiple applications.

The UK ETA stands out for its generous six-month stay allowance and straightforward application process. Apply for yours through the official portal or app, and use our application guide if you need help with the process.
